Although not as current as the source files, these downloads are pretty close in terms of actual content. The maps are lower res than the Item 100D printable set and lack the bonus information. Another big difference is that a portion of the proceeds from the sales of each Item 100D is donated to the Friends of the Smokies Fisheries Scholarship Fund. If you can't go the price of the product (SRP $59), please consider making a personal donation to the fund. Please designate the "Smokies Fisheries Scholarship Fund" is to recieve your gift on your check, online or by phone. As a personal favor, please mention you heard about the opportunity from Saint Clair Mapping on this message board. The web site is http://friendsofthesmokies.org. Phone: 865-932-4794.
